Silverado gas tank strap failure!!

[Big Block Bill]

We replace rusted brake & fuel lines all the time on anything over 5 years old. It doesn't matter if it is a GM, Ford, or Chrysler. I had a Tech leave me (Wife had health problems & needed to live in a warmer climate) and go to a Palm Bay Florida Chevy dealer. He says they get 2 year old cars & truck in all the time that are stored by the Ocean with rusted brake lines. GM says it is an "Environmental Problem" and NOT a design flaw, so they will not warranty the repairs. So its not just the "Rust Belt" vehicles that get rusty lines & straps
